The operation of nay-improvements is as follows: With the parts as shownthemovtive fluid, entering port 9, flows through the 1eft-handinlet-port 6 into the left-hand cylinder 2 to drive the piston 3 thereinoutward 5 and draw in the piston 3 in the right-hand cylinder to forceout the fluid from4 this cylinder through exhaust-ports 7 and 10. Whenpiston 3 in right-hand cylinder 2 reaches a position to bring .itsbumpennut 22 into conxo tact with the .spring 21, it compresses thespring until the resistance from motive. pressure on the opposite endsof valves and 16 is overcome, when yokes 13 will be swung to carry thevalves 15 and 16 to their reverse i 5 positions to open the right-handinlet-port 6 and left-hand exhaust-port 7 and reverse the flow of themotive fluid.

Water, steam, compressed air, or other fluid may be 'employed to drivethe motor, zov and hence I consider myself at liberty to employ anyfluid for the purpose, and I do not restrict myself to the precisedetails set forth, but consider myself at liberty to make such slightchanges and alterations as fairly fall within the s irit and scope of myinvention. Having fu ly described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1.v In a Huid-motor, the combination with 3o"eylinders arranged intandem, a valve-cham ber between them, istons in the cylinders, and arod secured to oth istons and extendin through the valve-chamber, ofhinged o es on the valve-chamber, inlet and exaust valves supportedsolely by said yokes and shifted thereby when the yokes are moved by themovementof the pistons.

2. In a fluid-motor, the combination with cylinders arranged in. tandem,a valve-cham-v 4o ber between them, pistons in the cylinders,

and a rod secured to both istons and extending through the valve-camber, of inlet and exhaust valves'in the valve-chamber, hinged'yokessupporting said valves, s rings 4 5 secured to said yokes, and means ont e rod.'

to engage the springs and throw the yokes and valves.

3. In a fluid-motor, the combination withl cylinders arranged in tandem,a valve-cham- 5o ber between them having a central horizontal partition,pistons inthe cylinders, and a rod secured to both pistons and extendingthrough'the valve-chamber, of an inletvalve in the valve-chamber abovethe partition, an exhaust-valve in the valve-ehamber below thepartition, hinged yokes supporting both valves, and means on the rod formoving the yokes.

4. In a iluid-rnotor, the combination with cylinders arranged in tandem,a valve-cham 6o ber between ,them having a central horizone talpartition, pistons in the cylinders and a rod secured to both pistonsand extending through the valve-chamber, of an inlet-valve in thevalve-chamber above the partition, an' 65 exhaust-valve in the chamberbelow the partition, inlet and exhaust ports in both ends of thevalve-chamber, adjustablev seats'in the r inlet-ports, and hinged yokeson the ends of n the valve-chamber affording the sole spport 7o for thevalves. l n" 5. vIn a fluid-motor. the combination with a valve-chamberhavin ports in its ends, of sleeves screwed into the ports -andconstituting adjustable valve-seats, a -valve be- 7 5 tween the portshaving contracted extensions proj ecting through the sleeves but outofconta'ct therewith, swinging yokes and screws thereon engaging the endsof t e :vaine extensions and supporting the valve'.

6. The combination with a valve-chamber having a horizontal partitiontherein andan inlet at its to 'and an exhaust at its bottom, of aninlet-va ve in the upper portion of the; chamber to alternately closeand open ports 8 5 in the ends of the chamber, an exhaustrvalve in thelower portion of the chamber to alternately open and close ports in theends of the chamber, yokes hinged to the ends of the chamber, screws insaid-yokes engaging lthe 9o ends of the valves and sup orting them, andsprings secured to said o es to receive the builing means to move t eyokes and valves.

In testimony whereof I have signed this specification -in the presenceof two subscribing Witnesses.
